    • Q

      What is the efficiency rating of SUNPAL Topcon Dual Glass Solar Panels?

      A

      These panels boast a high efficiency rating of up to 23.36%, meaning they can convert more sunlight into usable energy compared to lower-efficiency panels.
    • Q

      What is the temperature coefficient of these solar panels?

      A

      This BiMAX N-type module features an industry-leading temperature coefficient of -0.29%/°C. Unlike standard P-type modules (typically -0.35%/°C), this lower coefficient means the panel loses significantly less power as temperature rises. This ensures stable and high energy yield even in extreme heat environments, making it ideal for hot climates. Detailed performance curves are available in the datasheet.
    • Q

      How do these solar panels contribute to sustainability?

      A

      By choosing SUNPAL Topcon Dual Glass Solar Panels, you're investing in clean and renewable energy, reducing your carbon footprint, and contributing to a greener future.
    • Q

      Are SUNPAL Topcon Glass Glass Solar Panels easy to install?

      A

      While it's recommended to hire a certified solar installer, these double glass solar panels are designed for straightforward installation with standard mounting systems.
